The dragon plot is an anticlimax. The real arc of the book is the Thorin/Bilbo relationship. Truefax. I kind of forgot that so when I reread the book a while ago, I was like...huh. And now Thorin is hot and de-aged? Fandom, you better get ready.
Oh, I agree! See, it /used/ to be a crack ship for me. XD Mainly because I thought I was insane in pairing them and figured everyone else would find me idiotic. XD But, now that more people are pairing them, I don't feel as weird.
